Houston Intercontinental Airport Modifications and Reconstruction to “Whiskey Alpha” and “Whiskey Bravo” Taxiways

Klotz Associates designed the rehabilitation of two 12,000-foot concrete taxiways, “Whiskey Alpha” (WA) and “Whiskey Bravo” (WB) and a replacement of the west airfield lighting electrical vault.  The rehabilitation strategies accommodated for anticipated aircraft traffic including the Airbus A-380.  Designs incorporated multiple existing pavement sections in various states of disrepair.  The project included the integration of a centerline lighting system including coordination with FAA project for Runway Status Lights.  Also included were upgrades to the airfield lighting control system associated with the new lighting and vault.  Construction sequencing included development of multiple phases of construction to minimize disruption to airport operations.

TxDOT Aviation Gillespie County Airport Pavement and Electrical Improvements, Fredericksburg, Texas

Klotz Associates performed engineering / design services for Capital Improvements at Gillespie County Airport, located in Fredericksburg, Texas.  The improvements included the rehabilitation of the airside pavements; marking the runway, taxiway and aprons; replacement of the Medium Intensity Runway Lights (MIRL) along Runway (RW) 14-32; construction of a new helicopter apron and installation of game-proof fencing.  Klotz Associates prepared the preliminary engineering report, preliminary design, drainage analysis, final design, bidding and construction phase services.

Gillespie County airport primarily serves private pilots and business jets.  The proposed helicopter apron can accommodate two CH-47 Chinook Helicopters.  The Chinook is an American twin-engine, tandem rotor heavy-lift helicopter, and its primary roles include troop movement, artillery emplacement and battlefield resupply.

During the 2011 wildfires in Central Texas, Gillespie County Airport served as a base of operations for the Texas Forest Services Aerial Fire Support Team.  This included three retardant bombers and a helicopter that provided support to local fire fighters.

City of San Antonio Airport Wayfinding Signage Design Services, San Antonio, Texas
This project consisted of design and construction phase services for vehicular and pedestrian wayfinding signage for the San Antonio Airport. Signage included reuse of existing structures and installation of two to three new overhead signage structures. Terminal signage and "You are Here" signage was replaced in the short-term parking garage. Smaller signage along the road was elevated for replacement, relocation or removal. This project was fast-tracked to be only a 90-day design period and the project constructed within one year.

Montgomery County Lone Star Executive Airport in Conroe, Texas

The runway extension project at Lone Star Executive Airport has been awarded to Klotz Associates, Inc.  The airport is located in Montgomery County just out of Conroe.  The project consists of a 1,500-foot extension of the airport’s main runway. This extension will allow more aircraft to use the runway, especially in bad weather and wet conditions.  Along with the runway extension are many appurtenance improvements such as grading, airfield lighting, FAA equipment relocation, and adjacent pavement reconstruction.  The total construction cost is currently projected to be over $13 million and will take the next 3 years to design and construct.

TxDOT Aviation, Georgetown Municipal Airport - Engineering /Design Services, Georgetown, Texas

Klotz Associates Austin Office has been selected by the Aviation Division of the Texas Department of Transportation (TxDOT) and the City of Georgetown to perform Engineering / Design Services for a project at Georgetown Municipal Airport. The airport is considered to be an extremely important reliever facility within the Central Texas airport system. The project will include improving the Runway Safety Areas, rehabilitating the corporate taxiway and hangar access aprons, widening a taxilane and installing obstruction lighting. Estimated construction cost is $2 million.

Houston Airport System, George Bush Intercontinental Airport - Rehabilitation of Runway 15L-33R, Houston, Texas

The scope of this ongoing project includes design of concrete pavement replacement on 3,000 feet of runway as well as the bonded concrete overlay of 5,000 feet of existing concrete runway and connecting taxiways. Klotz Associates performed an analysis to determine the need for concrete overlay by using non-destructive pavement analysis and finite-element computation of pavement performance under anticipated aircraft traffic. This allowed determination of required pavement thicknesses and further crack-propagation analysis for confirmation of overlay thickness to ensure against pavement shoving. During design of the pavement overlay, the firm determined that additional requirements must be specified for installation of the overlay to ensure a full bonding of the overlay to the existing pavement.

Scholes International Airport, Galveston, Texas
For this project Klotz Associates strengthened the taxiway parallel to the primary north-south runway, which needed improvements to the GA apron areas. Also, the taxiways to the T-hangars were in need of replacement. The firm completed an investigation of the 40-to-50-year-old pavement on the taxiway and executed design for its total rehabilitation. Klotz Associates also developed construction plans, which included overlay and slurry seal of all GA pavement areas. VASI on Runway 17 was replaced with PAPI-4. Work on the project also included various signage improvements and development of a detailed construction phasing plan that would not shut down FBO (fixed-base operation) or GA operations. Klotz Associates also prepared the scope of work for surveying and for geotechnical services and secured fee proposals for it. The firm also prepared a fee proposal for all services and submitted it for review.
